High Safety
Can pass punch、impact of heavy 、 or impact at 150 ℃ etc…
Thermal Strive at 150℃
The surface is flat and hard, most suitable for ipad or two-way radio.
Long Cycle-life
300 times at 80%
High C-Rate
5C、10C、20C、30C or more can be obtained.
Characteristics of high & low temperature
Can be discharged at 60℃, and at the same time, can be discharged at -20℃ or -40 ℃, according to your demand.
Bad Side: High in Production Cost
The above technology can be adopted for all the sizes of our lithium polymer batteries; our small cells, curved and thin cells can pass all the safety test with special materials.
